Hi, I have a data frame with 6563 observations. I can run a regression with loess using four explanatory variables. If I add a fifth, R crashes. There are no missings in the data, and if I run a regression with any four of the five explanatory variables, it works. Its only when I go from four to five that it crashes. This leads me to believe that it is not an obvious problem with the data,

My WinXP client creates files and directories that are writable only by the file owner, not by the group to which that user belongs. There must be something all-too-obvious that I am overlooking here, but I'll be darned if I can find it. The files and directories can be read just fine, but I can't write to them. Clues? Help? Commiseration? Thanks, Jay -- When we are planning for

How about -- d is a vector as you described it, then define d1 <- d[1:(length(d)-1)] d2 <- d[2:length(d)] d3 <- d1!=0 & d2!=0 & (d1-d2)!=0 I think d3 is the final vector you wanted. I didn't test it, so I'm not sure my logic is right, but I think this is definitely a path you can take... -----Original Message----- From: owner-r-help at stat.math.ethz.ch
